It's easy to get accustomed to taking the various features and tools within Aperture at face value without really thinking any further about what they might have to offer. But if you're willing to think outside the box a tad, you may discover a lot of untapped potential. For example, on the surface, the Book tool in Aperture exists to let you create books from your images. As you know, there are options for various layouts, with and without text. You can opt to have Apple generate the books (and by the way, their quality is now quite impressive) or generate a PDF to send to the printer of your choice. But did you realize that you can use the Book tool to create posters or text slides for use in a slideshow?
